To all whom it may concern:

Be it known that 1, JOHN WV. OSBORNE, a citizen of the United States,residing at Winchester, in the county of Scott and State of Illinois,have invented certain new and useful Improvements in Cultivators; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to cultivator-s and particularly to that type whichare known in the art as straddle row cultivators.

One of the principal objects of the invention is the provision of novelmeans for equalizing the weight upon the frame so that when the driveris in the seat, the frame is practically balanced upon the axles andcomparatively little weight is thrown upon the saddles of the harness sothat less labor will be put upon the horses.

A further object of the invention is the provision of novel means forcontrolling the action of the plow beams and the turning disks andfurther means for causing the wheels to dodge the uneven corn.

With the foregoing and other objects in view, the invention consists ofcertain novel features of construction, combination and arrangement ofparts, as will be more fully described and particularly pointed out inthe appended claim.

In the accompanying drawings, Figure 1 is a top plan view of thisimproved machine. Fig. 2 is a side elevation thereof with the near wheelremoved. Fig. 3 is a rear elevation thereof. Fig. 4 is a horizontalsection taken on the line 1 1 of Fig. 2.

Referring more especially to the drawings, 1 denotes the tongue of thevehicle which is connected to the side members 2 of the frame by bearingstruts 3 and by diagonal braces 4: and 5. The side members of the frameare arranged substantially parallel and are connected together by crossbraces 6 and 7, the latter adapted to receive suitable operatingmechanism which will be hereinafter described.

The bearing struts 3 comprise attaching plates 8 which are bolted to thesides of the tongue 1 and have at either end thereof the dependingbearing arms 9, in which are j onrnaled the pivoting shafts 10 of theplow beams 11. These shafts 10 are provided with sleeves 12 journaledthereon and said sleeves have attached thereto right angular sleeves 13which are adapted to receive the ends of the plow beams so as to permittheir lateral movement with respect to the frame of the machine and thesleeves 12 being revolubly mounted upon the shafts 10 per mit thevertical movement of the beams.

Secured to the outer face of each side piece 2 are pivoting plates 14,upon which are pivoted the axle sleeves 15, normally held in a verticalposition as will hereinafter be described. These sleeves are adapted toreceive the axles 16, upon the lateral extension of which are mountedthe supporting wheels 17. The upper end of each axle is reduced andthreaded, as at 18, so as to receive the locking nuts 19 which hold thecontrolling levers 20 in position thereon ,to turn the axles within thesleeves. These levers are connected together by a cross brace 21 so thatthe wheels will be operated simultaneously as will now be described.

Pivoted to the underneath side of the cross brace 6, is a lever 22 whichextends rearwardly beneath the sleeve brace 23 and lies between thecross brace 7 and a guid- ,ing strip at mounted thereon. At the rearend, the lever is provided with a handle by which the device may beoperated, and intermediate its length, is provided with laterallyextending apertured ears 25 which are adapted to receive the connectinglinks 26 bridged between the lever 22 and the levers 20 on the axles. Inthis manner, by shifting the lever 22, the wheels 17 may be turned at anangle to the line of draft so as to dodge any crooked corn or for anyother similar purpose. The beams 1.1 extend back rearwardly insubstantial parallelism with the side members 2 for a short dis.- tanceand are provided with suitable clips 27 by which the plow standards 28may be secured thereto. The extreme ends of the beams are bentoutwardly, as at 29, so that the outer standards 28 will be offset fromthe inner standards which are connected to the straight portion of theplow beams, as described.

Forward of the inner plow standards, are secured the laterally offsetstirrup arms 30, upon the ends of which are mounted the foot stirrups31, by which the lateral position of the plow beams may be controlled bythe operators feet. These stirrup arms are connected, adjacent theirextremities, to the .plow beams by cross braces 32, and the offsetportion of each beam is provided with a brace 33 to prevent itsstraightening out when in action. At the bend of the beams, I secureupwardly projecting rods 34 which are provided with hand holds 35 attheir upper ends, by which the plow beams may The opposite ends of thespiral springs 39 are connected to the blocks 42, adjacent the forwardend of the frame and tend to normally raise the plow beams, through theaction of the bell crank levers and links just described.

Secured to the stirrup arms, adjacent their offset bend from the beams,are suitable guiding cleats 44, in which are mounted 1 Copies of thispatent may be obtained for five cents each, by

the standards 45 of the cultivating disks 46. These standards areconnected, by means of rods 47, to operating arms 48, in which theyslide. A series of apertures 49 are formed in the rods which are adaptedto receive pins 50 which hold spiral springs 51 surrounding the rods inthe proper degree of tension. The arms 48 are rigidly secured to asquared shaft 52 journaled in bearings 53 carried by the side members ofthe frame and are operated by an arm 54 carried by the shaft andcontrolled through the link 55 by the hand lever 56 which is pivoted tothe left hand side member 2 and adapted to operate over a suitablesegmental rack 57.

Upon pulling the lever 56 in a rearward direction, and locking it insuch position in engagement with the rack, the springs 51 are put undertension so as to throw the disks 46 into engagement with the ground.This action also looks the plow beams in position so that the plows arein engagement with the ground. Pivoted to the opposite or right handside member 2 and adapted to operate over a segmental rack 58, is a handlever 59 connected at its lower end to a link 60 which is in turnconnected at its opposite end to the depending arm 60 of a shaft 61journaled between the side members 2 and having at its opposite end asimilar depending arm 62. Both of these arms 60 and 62 are connected bymeans of links 63 with the lower end of the sleeves 15 so that anymovement of the lever 59 will cause a movement of the lower end of thesleeves in a direction opposite to that of the movement of the lever,thereby shifting the center of gravity of the machine, and thus enablingthe operator to properly balance the frame.

Extending laterally from either side of the tongue, immediately forwardof the frame, is a braced doubletree member 64 which has dependingapertured ends 65 adapted to receive swingletrees 66, by which thevehicle is drawn. Suitable chains 67 are connected to the plow beams andto the axles so that their lateral movement opposite from their adjacentaxle may be limited. At the rear end of the side members 2, there areprovided bearing seats 68 having projecting up from their upper facesthe pins 69, which are adapted to enter suitable apertures 70 formed inthe outer ends of the seat supporting spring 71. The seat 72 is rigidlysecured to the center of this spring and is arranged in such positionthat the operator may place his feet in the stirrups 31 and grasp thehand holds 35.

From the foregoing description, taken in connection with theaccompanying drawings, the construction and operation of the inventionwill be readily understood without requiring a more extendedexplanation.

Various changes in the form, proportion and the minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention, as defined in theappended claim.

Having thus described my invention, what I claim is:

The combination with a frame consisting of side bars and cross barsconnecting thesame, of plow beams pivotally connected at their frontends to the frame, bell crank levers fulcrumed on a cross bar of theframe and having their opposite arms extending respectively forwardlyand downwardly from said-cross bar, coiled springs secured to thedownwardly extending arms and to the frame in advance of the same, linksconnecting the plow beams with the ends of the forwardly extending arms,a rock shaft on the frame in advance of the bell-crank levers, guidesrigid with the rock-shaft,

arms offset from and rigid with the plow beams, standards rising fromsaid offset arms and yieldably connected to the guides, and means on theframe for oscillating the rock shaft.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
